Dissolved Oxygen

In the graph below, "Data" are the raw data, "No supersat." are
the hourly data with a ceiling of 100% saturation, "7-day mean min"
represents the 7-day running average of daily minima with no credit for
supersaturation, and "30-day mean" is the 30-day running average with no
credit for supersaturation. The red line will often plot on top of the
black one. If the 7-day or 30-day lines are not plotted, it is due to
missing data in that period. "Saturation" represents the 100% saturation
value for dissolved oxygen.
